INTEGRATED CONNECTION UNIT IN AN UNDERWATER TELECOMMUNICATIONS SYSTEM, SUCH AN UNDERWATER TELECOMMUNICATIONS SYSTEM AND METHOD FOR RECONFIGURING SUCH AN UNDERWATER TELECOMMUNICATIONS SYSTEM

摘要

The present invention relates to a connection unit (10) which can be integrated into an underwater telecommunications system comprising at least three cables having optical and electrical transmission elements, the unit comprising: three terminals (A, B, C ) connected to the electrical transmission elements of the cables, three input points (E1, E2, E3), three electrical contacts (7 to 7 "), each being placed between one of the terminals and one of the input, reconfiguration means (26) capable of controlling the electrical contacts for switching, voltage measurement means (23) arranged to measure a voltage (U1) informing of the potential of a point of the trunk segment (P12) , any so-called optical reconfiguration request being made using an optical signal known as a reconfiguration signal, means of reception and processing (21) of optical reconfiguration signals (SrA, SrB, SrC), means of reconfiguration validation (2 5), capable of activating said reconfiguration means in accordance with said optical reconfiguration signal (SrB), only when the absolute value of said potential is below a threshold. /P
